Pitch and Footprint for the Board Layout
The 1744418-4: This is the standard Economy Power 2.5 spacing, so the mating receptacle and crimp terminals share the same pitch. Four positions loaded all, single row, vertical through-hole orientation. The kinked solder tails (0.134" post length) provide retention during wave solder and keep the header seated before the joint solidifies.
Shrouding and Locking for the Harness Fit
Board guide and glow wire compliant features are included. The glow wire rating (likely per IEC 60695-2-11) is a safety requirement for lighting and appliance applications where the connector may see fault current.
ROHS3 compliant. The base product number is 1744418, which covers the family of single-row, 2.50 mm pitch headers in this series.
